Objective:To explore the curative effect of acupuncture combined with huanglian wendan decoction on the mild cognitive impairment after stroke.Methods:100 patients with mild cognitive impairment after stroke were enrolled in our hospital from June 2013 to August 2016 and randomly divided into two groups.The control group (n=50) accepted nimodipine,and the study group (n=50)accepted huanglian wendan decoction combined with acupuncture treatment based on the control group.The MMSE and MSSS scores were evaluated and compared,and the improvement of cognitive dysfunction and nervous dysfunction,quality of life were compared and analyzed.Results:After treatment,the MMSE,ADL scores of patients were remarkably decreased compared with those before treatment (P＜0.05),and the decreasing degree of study group was significantly higher than those of the control group (P＜0.05).The MSSS,MBI scores of both groups were significantly increased compared with those before treatment (P＜0.05),and the increasing degree of study group was significantly higher than those of the control group (P＜0.05).The effective rates of improvement in cognitive dysfunction and nervous dysfunction,quality of life of study group were significantly higher than those of the control group (P＜0.05).Conclusions:Huanglian wendan decoction combined with acupuncture treatment was effective for the mild cognitive impairment after stroke and could improve the quality of life.

Objective:To explore the impact of sleep duration, physical exercise, and their interactions on the risk of dyslipidemia in older adults aged ≥80 (the oldest old) in China.Methods:The study subjects were the oldest old from four rounds of Healthy Aging and Biomarkers Cohort Study (2008-2009, 2011-2012, 2014 and 2017-2018). The information about their demographic characteristics, lifestyles, physical examination results and others were collected, and fasting venous blood samples were collected from them for blood lipid testing. Competing risk model was used to analyze the causal associations of sleep duration and physical exercise with the risk for dyslipidemia. Restricted cubic spline (RCS) function was used to explore the dose-response relationship between sleep duration and the risk for dyslipidemia. Additive and multiplicative interaction model were used to explore the interaction of sleep duration and physical exercise on the risk for dyslipidemia.Results:The average age of 1 809 subjects was (93.1±7.7) years, 65.1% of them were women. The average sleep duration of the subjects was (8.0±2.5) hours/day, 28.1% of them had sleep duration for less than 7 hours/day, and 27.2% had sleep for duration more than 9 hours/day at baseline survey. During the 9-year cumulative follow-up of 6 150.6 person years (follow-up of average 3.4 years for one person), there were 304 new cases of dyslipidemia, with an incidence density of 4 942.6/100 000 person years. The results of competitive risk model analysis showed that compared with those who slept for 7-9 hours/day, the risk for dyslipidemia in oldest old with sleep duration >9 hours/day increased by 22% ( HR=1.22, 95% CI: 1.07-1.39). Compared with the oldest old having no physical exercise, the risk for dyslipidemia in the oldest old having physical exercise decreased by 33% ( HR=0.67, 95% CI: 0.57-0.78). The RCS function showed a linear positive dose-response relationship between sleep duration and the risk for hyperlipidemia. The interaction analysis showed that physical exercise and sleep duration had an antagonistic effect on the risk for hyperlipidemia. Conclusion:Physical exercise could reduce the adverse effects of prolonged sleep on blood lipids in the oldest old.
